I didn't get a chance to look for the file last night, but the poses are part of a full Wolverine figure (the older yellow/blue costume), not specifically a pose pack and the filename is wolverine.zip. This file is an oldie that I downloaded six years ago and I haven't checked if it's still available at Animotions, but it should be. I noted, in my index, that the readme was not specific about copyright usage.
